Enteric nervous system

Parkinson’s disease is a condition from the nervous system that disturbs motion throughout the human body. It progresses bit by bit. In the beginning of this condition, Parkinson’s disease can be seen by people who are diagnosed with this. They appear to seem as if they have no communication on their faces. They speak quite unclear and quiet. As the disorder develops throughout time, the signs worsen and are more transparent. This disorder has no cure but medicine is highly involved factor in…

Almost all multicellular organisms contain a nervous system, which allows them to sense changes in their environment or induce muscle contractions through electrical impulses. The majority of nerves cells that make up the nervous system are excitable cells, as they have the ability to produce an electric current to formrom an action potential from using a concentration gradient of ions across their membrane (Sherwood, 2013). The current generated by the flow of sodium (〖Na〗^+) and potassium (…

Parkinson’s Disease Briana Rogers Denver School of Nursing Abstract This paper will discuss Parkinson’s Disease (PD). The pathophysiology, assessment findings, and treatments/diagnoses will be explored. PD is a chronic disease that affects the way your body moves, causing uncontrollable movements. The pathophysiology of PD is idiopathic (having no known cause), but symptoms are known to indicate the disease. We know what happens when PD invades the brain, but we don’t know why. PD is caused…

Neuroimaging is defined as a “set of tools that produce pictures, of the brain, sometimes called brain scans” (). There are two specific types of neuroimaging: functional and structural. Functional neuroimaging looks for brain activity by measuring the amount of oxygen that changes in the blood, electrical impulses or chemical activity. Structural imaging generates pictures inside of a head, that includes pictures of bones, brain tissues, blood vessels and fluid of the brain and spine.…

eating foods rich in glutamic acid and glutamate. You can also stimulate your body to produce serotonin by eating foods rich in tryptophan. GABA and Serotonin act as gatekeepers in the body. GABA is the chief inhibitory neurotransmitter of the nervous system. GABA is also involved in the production of endorphins, brain chemicals involved in the feeling of happiness. (Onedietandhealth.com) GABA and Serotonin are counterparts to Dopamine and Acetylcholine that allow us to move, act, focus and…

Researchers experiment with brain cells to understand the different pathways. As the follow experiment where researchers put glutamate in a culture where there were neurons and astrocytes. After a glucose use by cells, they saw an inhibition of the glucose transport into the neurons and this inhibition was stronger with add of lactate in the culture. This experiment show us that glutamate inhibited glucose transport into the neurons and in consequence inhibited glycolysis, and this is why it…

Zebrafish embryos are suitable to use as a model system to perform chemical biology experiments effectively in educational sites. In this experiment, we studied the effect of caffeine on heartbeat rate and other phenotypes of zebrafish embryos using visual microscopy and simple imaging. A small drop for concentrations of caffeine in embryo medium caused an amount-dependent decrease in heartbeat rate in 2-3-day-old zebrafish embryos, finally resulting in complete heartbeat stop. We observed the…

In this experiment, we investigated electrically stimulated nerves n the forearm to display recruitment, summation, tetanus and conduction velocity of action potentials. Muscle are either directly joined to the bone or connected by tendons, which by definition are resilient bundles of collagen fibers. Motor nerves innervate the fibers of the skeletal muscles, which is controlled voluntarily. The action potential in a muscle fiber allows for an increase in the influx of calcium causing what we…

is a discipline, it makes very important contribution to the nervous system. I will be briefly going over biological bases of behavior and the mental processes. The first thing I will be talking about is endorphins. The second thing I will be talking about is the sympathetic nervous system, and the parasympathetic nervous system. The first thing I’m going to talk about is endorphins. Endorphins are produced by the central nervous system. Endorphins act like a morphine, or heroin, they are…

Music programs are being cut from an increasing number of schools across the country each day. Making the choice to rid a school of its music program is like making the choice to rid a school of its education all together. Music in schools is much more than an elective, and few people know this. It is a tool that affects students in a way that will help them succeed and become more intelligent members of society. It alters the way the brain develops, the way someone learns, and strengthens…
